Detailed Description

In order to better understand the technical solutions provided by the embodiments of the present application, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.

The information carried on each key in the traditional keyboard is generally in a single dimension, taking the traditional full keyboard as an example, each key generally corresponds to information in a single dimension, such as numbers or letters, when the information is input by using the single-dimension keyboard, the corresponding relation between each input operation and the input information is very clear, and the input information can be clearly known by peeping the input operation. Even if information in two dimensions is carried on an individual key, special control keys are required to be matched for operation during input, for example, numbers and operators on a full keyboard are usually arranged on one key, but when information is input by using the key, shift keys are required to be matched, so that which information to be input can be clearly displayed. In the case of inputting a password using a mobile terminal device such as a mobile phone, the keypad setting for inputting the password is simpler, and is generally composed of 10 number keys of 0 to 9, as shown in fig. 1. Assuming that the user uses the mobile phone to sequentially input each number constituting the password on the password authentication interface, the bystander only needs to see the whole input process, the password input by the user can be easily known, or the password input by the user can be easily and secretly photographed by adopting a candid photographing technology. Therefore, it is required to improve the security of the password, and even if a bystander intentionally observes or even records the video, the password can still be input in public without causing information leakage.

In order to improve the security of the password, the application provides a technology for performing password verification by using a multi-dimensional password, and in order to facilitate understanding of the technical scheme of the application, a plurality of technical improvement points provided by the application are firstly introduced in detail.

1. Multi-dimensional keyboard and multi-dimensional password

A multi-dimensional password is a password that constitutes a password, not a single dimension, but a combination of dimensions, a single dimension password is common, for example, a digital password, and the digital password may include multiple digits, for example, 6 digits or 8 digits, and is arranged according to a set order, where the password is verified successfully when the size and the ordering of each digit are correct. The multi-dimensional password is expanded on the basis of a single-dimensional password, the elements used as the password can be mixed passwords with different dimensions, the existing common passwords such as mixed numbers and letters are also common two-dimensional passwords with mixed numbers and letters, the common full-keyboard input is generally adopted, a unique password is correspondingly input when a key is selected each time, the password can still be easily observed, and no improvement is caused in the aspect of peeping prevention.

Along with the development of digital technology, mobile terminal devices generally use a touch-controlled digital keyboard as a password input keyboard, multiple pieces of information can be displayed on the digital keyboard at the same time, and the displayed multiple pieces of information are flexibly transformed according to set display rules. On the basis of the embodiment of the application, a multi-dimensional keyboard is provided, and a plurality of dimensions are arranged on each keyboard to be used as information of a password, for example, numbers, letters and colors can be displayed on the same key at the same time, for example, as shown in fig. 2 a. The dimensions displayed on each key may be single or multi-dimensional, such as shown in fig. 2B, with the keys displaying the number 0 being single-dimensional, the keys displaying the number 2 and the letter B being two-dimensional, etc. The password dimensions may be selected from a variety of forms, and in order to increase the difficulty of preventing peeping, some of the password dimensions may be displayed in a particular mode, for example, the color dimension may be displayed using a corresponding color. On this basis, the passwords with some dimensions can be displayed in a combined mode, for example, as shown in fig. 2c, after the colors and the graphics are combined, the colors are not displayed in the form of Chinese characters, but are displayed in the form of background colors in the graphics, in fig. 2c, the background colors in the graphics circles are orange colors which represent orange passwords in the color dimension, the background colors in the triangles can be yellow which represent yellow passwords in the color dimension, and the like, and one background color is added in the graphics passwords on other keys to represent the corresponding color passwords. Each digit can be displayed in a different color on a digit basis, and represents a password of the digit color dimension. The above-mentioned dimensions include a digital dimension, a digital color dimension, a graphic dimension, a background color dimension, etc., but may be any other dimension commonly used, such as various pets, fruits, etc. The password formed by the multi-dimensional information is called a multi-dimensional password, and the keyboard displaying the multi-dimensional password forms a multi-dimensional keyboard. The specific display mode adopted by the password of each dimension can be varied, and the application is not limited.

Because a plurality of passwords are displayed on each key, bystanders can know the key selected by the user, and can not determine the dimension of the password input by the user, so that the security of the password input is greatly improved, the password decoding difficulty is also greatly improved, and the password decoding is difficult under the condition of no peeping. Taking three-dimensional password as an example, referring to fig. 2c, as an example of three-dimensional password displayed on a mobile phone terminal, three dimensions may include a number dimension, a graphic dimension and a color dimension, wherein the password of the number dimension is 10 integer numbers of 0 to 9, the password of the graphic dimension includes 10 graphics, such as a circle, a triangle star, a trapezoid, a square, a semicircle, a heart, a pentagon, a regular hexagon, an star of star and a hexagon, the color dimension includes 10 colors, and the 10 colors are respectively displayed in a pattern of background colors of the graphics, such as orange, yellow, green, lake green, light pink, red, deep blue, purple, deep pink and gray. The number of passwords in each dimension is the same as the number of keys, the passwords are respectively displayed on one key, and the number of the passwords displayed on each key is 3.

Referring to fig. 2a, fig. 2b and fig. 2c, the multi-dimensional password keyboard provided by the application can be obtained by expanding the existing single-dimensional number password keyboard, and each key can represent a number password as well as any other password in any dimension. Therefore, the keyboard can be used as a common single-dimensional digital code keyboard, can also be used as a multi-dimensional code keyboard with two dimensions and even higher dimensions, is compatible with the existing digital code keyboard, and has a very simple operation mode. When the number of the password digits is the same, each dimension is increased to enable possible password combinations to be increased in geometric progression, so that the difficulty of password decoding is increased, and the peeping prevention effect is achieved.

It should be noted that the multi-dimensional keyboard shown in fig. 2a, 2b and 2c is only an example, and the present application is not limited to the number of keys of the multi-dimensional keyboard and the arrangement of the keys. For example, the multi-dimensional keyboard comprises N keys, the multi-dimensional password comprises M-dimensional passwords, each dimension comprises at most K passwords, and at least one password is displayed on each key. If K is equal to N, the number of passwords displayed on each key is M.

The principle of the multi-dimensional cipher keyboard provided by the application in the cipher using process is further described below by taking a four-dimensional keyboard as an example.

As shown in FIG. 3a, the number of keys N and the number of passwords K in each dimension are equal to 10, the number of the dimensions M is equal to 4, and the multi-dimension password shown in FIG. 3a is based on the three-dimension password shown in FIG. 2c, and a fourth dimension is added: the number color dimension forms a four-dimensional password, and the keyboard correspondingly displaying the four-dimensional password is called a four-dimensional keyboard, wherein the four-dimensional keyboard comprises 10 keys in total, and 4 passwords with different dimensions are distributed on each key. In fig. 3c, a feature value is also set for each password, and the transmission of the password checksum password information is performed by using the feature value corresponding to the password, which is described in detail in the following specific embodiments.

One display mode of the four-dimensional password is shown in fig. 3a, wherein the background color is displayed in the graph, and the digital color is used for displaying the digital mark in different colors. For example: the number 1, the gray number, the triangle and the background red are displayed on one key; the number 3, purple number, pentagon, background yellow is displayed on one key; number 5, red number, hexagram, background green on one key, etc.

Referring to fig. 3a, assume that the scenario: the user uses the four-dimensional keyboard provided by the embodiment of the application to sequentially select the following 6 keys: number 3 key-number 5 key-number 1 key-number 8 key-number 2 key-number 7 key. Depending on the order of selection of the keys, a group of passwords entered through a multi-dimensional keyboard may be combined in a number of ways, up to 4 possible combinations of passwords ⁶ I.e., 4096, the combination of passwords is nearly 4000, even though the possibility that the same color number is displayed on the same or similar background color is eliminated. The possible combinations can be either single-dimensional passwords or multi-dimensional hybrid passwords. A one-dimensional password is, for example, a password that is entirely composed of numbers: '3, 5, 1, 8, 2, 7', multi-dimensional passwords such as: '3, background red, graphic triangle, 8, 2, 7', 'graphic pentagon, 5, 1, graphic trapezoid, background orange, 7', or 'background yellow, background cyan, background red, background powder, background orange, background violet', etc. For a five-dimensional or higher-dimensional keyboard, the combination forms of the passwords are more and are difficult to decipher, so that the purpose of preventing the passwords from being peeped and leaked is achieved.

The example of each multi-dimensional keyboard is that passwords of other dimensions are added on the basis of a single-dimensional digital password keyboard, the numbers of passwords of each other element are 10, the passwords of each dimension are respectively displayed on different keys, the passwords displayed on the same key are respectively of different dimensions, and the numbers of the passwords displayed on each key are the same. However, it should be noted that, in the multi-dimensional password provided by the embodiment of the present application, the number of passwords in each dimension may be different, and it is not limited that each password displayed on the same key belongs to different dimensions. For example, in a three-dimensional password, the number dimension is 10 passwords, the number of the color dimension is only 8, and the number of the figure dimension is only 5. In this case, at least 1 password is displayed on each key. If the passwords defining each dimension can only be displayed on different keys respectively, a maximum of 3 passwords are displayed on one key. Of course, the same mode of the number of passwords displayed by all keys can be adopted, and passwords with some dimensions can be displayed twice. For example, 5 passwords in the graphic dimension, each password can be displayed on two keys at the same time when displayed each time, and two passwords in 8 passwords in the color dimension can be displayed on two keys at the same time.

2. Dynamic display of multi-dimensional keyboards

Because the multi-dimensional keyboard provided by the application comprises one or more passwords displayed on each key, when the passwords are input, the passwords input by a user cannot be uniquely determined through one operation. The embodiment of the application provides a dynamic keyboard display technology, wherein a dynamic adjustment algorithm is adopted, in all keys of a multi-dimensional keyboard displayed twice, at most one password is the same in passwords displayed on any two keys, the passwords displayed on any two keys displayed at the same time do not have the same password, and only one intersection is allowed at most in passwords displayed on two keys at different times. Thus, the user selects a plurality of keys each time according to the number of digits of the passwords, and the intersection of the passwords displayed on the same ordered key is only contained in one password according to the selection order. And then, through twice input, the passwords displayed on the two keys with the same sequence in the twice selection sequence are intersected, so that the unique password corresponding to each sequence can be obtained, and after the obtained passwords are combined according to the sequence, the password input by the user can be obtained. For example, as shown in fig. 3a and 3b, an example of two consecutive displays of a four-dimensional code keyboard is shown, in which the background color, the number color, and the graphic displayed on two keys with the same number are different.

In the embodiment of the application, if the keys selected by the multi-dimensional keyboard are used twice, a unique password can be obtained for each key with the same sequence, so that the accuracy of inputting the password by the user is ensured to a great extent, and further verification is not needed. Of course, to further ensure security, a third input may be performed, and the password input by the user may be obtained again by the third input and the first input, or the password input by the user may be obtained again by the second input and the third input, and the previously obtained password may be verified.

For example, with a four-dimensional 6-bit password, when the user enters the password for the first time, the password displayed on the first selected key comprises: 'graphic pentagon, 5, background orange, digital color red', when the user inputs the password for the second time, the password displayed on the first selected key comprises: 'graphic triangle, 7, background green, digital color red', then among the passwords entered by the user, the password ordered first is the intersection of the two: the digital color is red.

When the keyboard is displayed by adopting the dynamic keyboard technology, the displayed passwords on each key are adjusted when the multidimensional keyboard is displayed each time, so that the requirement of at most one same password is met, the display positions of each key can be disturbed, and the sight of a peeper is further disturbed. The display position of each key can be flexibly set according to the display screen and the requirement of the page interface, for example, the mobile phone terminal mode shown in fig. 4a comprises 10 keys which are divided into four rows, 3 keys are respectively arranged in the first three rows, and the last key is arranged in the middle of the fourth row. If the display mode shown in fig. 4a is referred to as a regular display, based on the ordering of the number codes, then fig. 4b is an example of an out-of-order display mode. In the conventional display mode of fig. 4a, the display positions of 10 number ciphers 0 to 9 in the number dimension are arranged sequentially from left to right in each row. In the out-of-order display mode shown in fig. 4b, the display positions of the respective digital passwords are disturbed, and the degree of disturbance of the out-of-order display mode is greater, so that the security is higher. The disorder is illustrated by taking a common single-dimensional digital password as an example, and the password display position of any one dimension can be used as a discrimination reference of a conventional mode and a disorder mode after other dimensions are added.

In the embodiment of the application, when a user sets a password or uses the password, the user inputs the password by adopting a multi-dimensional keyboard, the process of inputting the password is the process of selecting keys on the multi-dimensional keyboard, because a plurality of passwords are displayed on each selected key, when the user inputs the password each time, a group of password collection sequences are actually input, for example, the user sets L-bit reference passwords, L keys are required to be selected each time when the password is checked and input, the password collection displayed on the L keys is combined according to the key selection sequence to form an L-bit password collection sequence, and each password collection is contained in at least one check password. For example, if the first reference code of the L-bit reference code set by the user is the number 5, when the user inputs the check code, the code displayed on the first selected key includes the number 5, and if the first check code is correctly input, and if all the L-bit check codes are correctly input, the code check is successful.

The user also needs at least two setting operations to determine the reference password set by the user when setting the reference password. It is also possible to determine what the password is in particular for each bit of the verification password by performing the password input operation at least twice when the verification password is input. Therefore, in order to determine that each of the check passwords inputted by the user is unique through at least two operations, any two passwords displayed on the same key of the multi-dimensional keyboard are at most the same, so that the unique password can be determined according to the intersection of the two inputs. It should be noted that, at least two times herein generally refers to a process of performing verification by using a verification password and setting a password in a single business process. Of course, between adjacent business processes on the same terminal, the passwords displayed on the same key at any two times are kept to be the same as much as possible, so that peeping is further prevented.

The process of setting the reference password before the service is used by the user is basically the same as the process of inputting the check password by the user in the service use, and the dynamic display technology of the multi-dimensional keyboard is used as support.

Based on the multi-dimensional password, the multi-dimensional keyboard and the dynamic display technology of the multi-dimensional keyboard, the password verification method provided by the embodiment of the application can be used in any business needing password verification, the system architecture for realizing the business is shown in fig. 5, and the application scene comprises terminal equipment (101, 102, 103) used by a user and servers (120, 130) of a business provider. The terminal device and each server can communicate through a communication network, and each server can also communicate through a communication cable. The communication network may be the internet, a wireless network or a mobile communication network. The terminal device may be a mobile phone 101, a desktop computer 103, a notebook computer 102, or other terminals with mobile communication functions, such as various wearable devices.

The password verification technology provided by the embodiment of the application is mainly used in the businesses needing to use passwords, servers in the businesses can be divided into an authentication server 120 and a business server 130 according to functions, the authentication server 120 stores a reference password set by a user through terminal equipment (101, 102 and 103), when the user requests the businesses, the passwords to be verified input by the user are verified according to the reference password, and if verification is successful, the business server 130 provides corresponding business services for the user. It should be noted that the authentication server 120 and the service server 130 may be combined. The terminal device set by the service provider for the user may also be combined with the authentication server 120 or the service server 130.

The technical scheme provided by the application mainly comprises two processes of setting a reference password and inputting a verification password for password verification by a user, and is respectively and specifically described with reference to a flow chart. The service process to be executed after the password verification is successful, according to different services, common password verification such as password verification needed during payment, password verification needed during logging in an application, and the like, the password verification technology provided by the embodiment of the application can be applied to a plurality of scenes, and various application scenes are well known to those skilled in the art and are not repeated here.

As shown in fig. 6a, fig. 6a is a process of setting a 6-bit reference password of a user on the authentication server 120 through the terminal device 103, and mainly includes the following steps:

s601, the terminal equipment 103 responds to the reference password setting operation of a user, and a multi-dimensional keyboard is displayed on a password setting interface for the first time;

before setting the reference password, the user needs to enter a password setting interface through the terminal device 103, and the terminal device 103 displays a multi-dimensional keyboard on the password setting interface according to the operation of setting the password by the user, and the password setting interface is shown in fig. 6b for example.

Step S602, a user sequentially selects key inputs on a multi-dimensional keyboard to perform first input, and presses a confirmation key after finishing the input;

the user sequentially selects keys on the multi-dimensional keyboard according to the multi-dimensional password combination mode created by the user, and the keys with the passwords correspondingly ordered are selected and displayed according to the selection sequence. According to the operation of selecting the keys by the user, prompting information such as asterisks appears in a password frame on the password setting interface every time one key is selected, so that the ordering of passwords input by the user is prompted.

In step S603, the terminal device 103 obtains the password setting information input by the user on the multi-dimensional keyboard for the first time, the password setting information input for the first time including the password set displayed by each key selected by the user and the order in which the keys are selected by the user.

Step S604, the terminal device 103 sends the password setting information input by the user for the first time to the authentication server 120;

in this embodiment, 10 different passwords are selected for each dimension, see fig. 3 c:

first dimension, digital dimension: (0-9);

second dimension, digital color dimension: (red/orange/yellow/green/cyan/blue/violet/powder/gray/black);

third dimension, graphic dimension: graphics (triangle star/square/regular pentagon/regular hexagon/octagon/dodecagram/trapezoid/heart/circle);

Fourth dimension, background color dimension: background color (red/orange/yellow/green/cyan/blue/violet/powder/gray/black), which may be identified in the graphical element.

For example, according to the multi-dimensional keyboard shown in fig. 6a, the set of passwords displayed in position 3 is as follows: number dimension 3, number color dimension purple, graphic dimension regular pentagon, background color dimension yellow. If the password selected by the user is one of the four, the key at the position 3 is selected.

Referring to fig. 3c, in order to facilitate storage and transmission of password information, in the present application, feature values are correspondingly set for each dimension of passwords, the feature values of each dimension are different from each other, the selected password set on each key can be replaced by the feature values of four different dimension passwords, and in order to more clearly identify the feature values of the multi-dimension passwords, the feature values of different dimensions can be represented by numbers or letters.

In the password setting information sent to the authentication server, the terminal device 103 displays a corresponding set of feature values on each selected key, respectively, the feature value sets being arranged in the key selection order.

Step S605, the authentication server 120 stores the password setting information received for the first time;

In step S606, the terminal device 103 displays the multi-dimensional keyboard for the second time according to the user' S confirmation key operation information.

The second displayed multi-dimensional keyboard is compared with the first displayed multi-dimensional keyboard, and the password set displayed on each key of the second time is respectively compared with the password set displayed on each key of the first time, so that at most one identical password is allowed. Such as the two displays of fig. 3a and 3 b.

Step S607, the user sequentially selects keys on the multi-dimensional keyboard to carry out the second input, and presses the confirmation key after the input is completed;

in step S608, the terminal device 103 obtains the password setting information input by the user on the multi-dimensional keyboard for the second time, where the password setting information input by the user for the second time includes the password set displayed by each key selected by the user and the order in which the keys are selected by the user.

Step S609, the terminal device 103 transmits the password setting information input by the user for the second time to the authentication server 120;

step S610, the authentication server 120 stores the password setting information received for the second time;

in step S611, the right server 120 obtains the reference password set by the user based on the password setting information of the first time and the password setting information of the second time.

The password setting information is transmitted and stored in the form of feature values, and the authentication server 120 determines intersections of feature value sets with the same order according to the first password setting information and the second password setting information, wherein only one feature value exists in each intersection, and passwords corresponding to the feature values form a reference password set by a user. In this embodiment, the reference password set by the user includes 6 passwords, and according to the order of the passwords in the reference password, the intersection of the password sets displayed by the keys in the two inputs with the same order is respectively. As the multi-dimensional keyboard displayed for the second time is at most the same as the multi-dimensional keyboard displayed for the first time, the fact that only one password is displayed in the intersection is ensured.

Step S612, if a certain intersection is empty, it is indicated that the second time of input information is wrong compared with the first time, and the prompt information of failure in setting is returned, otherwise, the prompt information of success in setting is returned.

In step S613, after receiving the prompt message of successful setting, the terminal device 103 may prompt that the setting is successful on the user setting interface, and then end the setting flow. After receiving the indication information of the setting failure, the terminal device 103 displays the indication information on the user password setting interface and prompts the user whether to reset.

Steps S607 to S611 may be executed again according to the flow, to require the user to perform the third input, where the third displayed multi-dimensional keyboard also meets at most one same dynamic display requirement as the first displayed multi-dimensional keyboard. In order to ensure the effectiveness of verification, the third-time displayed multi-dimensional keyboard is compared with the second-time displayed multi-dimensional keyboard, and the password set displayed on each key is respectively compared with the password set displayed on each key displayed on the second time, so that only one identical password is allowed at most.

The authentication server 120 obtains again the reference password set by the user according to the password setting information received for the first time and the password setting information received for the third time, compares whether the reference password is the same as the previously obtained reference password of the user, returns indication information of successful setting to the terminal device 103 if the reference password is the same as the previously obtained reference password, and returns indication information of failure setting to the terminal device 103 if the reference password is not the same as the previously obtained reference password.

The interface for successful password setting is shown in fig. 6c, and the user can directly log in the service system or select to finish.

According to the above procedure, the user may set a four-dimensional 6-bit reference password by using, for example, a four-dimensional keyboard as shown in fig. 3a, and the authentication server stores the characteristic value combination of the four-dimensional 6-bit reference password for later verification, for example, when the characteristic value combination of the four-dimensional 6-bit reference password is 3hxC J according to, for example, fig. 3c, the corresponding reference password is: number 3, number color violet, pattern trapezoid, background color powder, number 0 and background color black. The correspondence among the password dimension, password and characteristic value of the four-dimension 6-bit reference password is shown in fig. 6 e.

The design and the use method of the multi-dimensional password keyboard are basically the same as those of the traditional single-dimensional keyboard, and a touch screen input mode can be adopted, and four dimensions are taken as an example.

The key display interface of the first input is shown in fig. 3a, and the key display of the second input is shown in fig. 3b when the password is set. According to the set four-dimensional 6-bit reference password 3hxC J, when the password information is input by using the multi-dimensional keyboard shown in fig. 3, the terminal equipment records the password characteristic values input on the keys of the keyboard from the first bit to the sixth bit when the password information is input for the first time, and the password characteristic values are recorded as A1, A2, and the first to the sixth bits; and inputting the password characteristic values of the first to sixth bits on the keys of the keyboard for the second time, wherein the password characteristic values are recorded as B1, B2. The key and its password feature values of the first and second inputs are shown in fig. 6f, and the background color and the number color are described in the table shown in fig. 6 f.

And respectively comparing An and Bn (n=1, 2,.. 6), acquiring intersection sets of the An and the Bn as respectively 3, g, u, h, 0 and j of the unique same dimension passwords in the An and the Bn (n=1, 2,.. 6), and recording 3guh j as a four-dimensional 6-bit reference password input by a user.

It should be noted that, an application program of a specific service is running on the terminal device 103, and each step of processing by the terminal device 103 is that the application program is specifically executed. The terminal device 103 may also obtain the reference password set by the user and send the reference password to the authentication server 130 for saving according to the password setting information input by the user for the first time and the password setting information input by the user for the second time. Further, the terminal device 103 may further obtain the reference password set by the user again according to the password setting information input for the first time and the password setting information input for the third time, and after confirming that the password setting is successful, send the reference password set by the user to the authentication server 130 for saving. And the terminal device 103 may also store the reference password set by the user by itself, and verify the verification password input by the user according to the reference password set by the user when the user logs in the service system. Either the authentication server 130 or the terminal device 103 may store the user's reference password in a local, blockchain or cloud disk file in an encrypted manner. The procedure of modifying the reference password by the user is the same as the procedure of initially setting the reference password, and a description thereof will not be repeated.

Referring to fig. 6d, when setting the password, a selection operation of increasing the password dimension corresponding to the input operation of each reference password may be performed, so that the reference password may be set by one input. Of course, the calibration of the reference password can be added by one input. The selection operation of the password dimension can be selected and confirmed in a pull-down menu mode.

As shown in fig. 7, a flow chart of verification by using a password when a user logs in a service system mainly includes the following steps:

s701, the terminal device 103 displays a multi-dimensional keyboard on the password input interface in response to a request for inputting a password to be checked by the user.

The password entry interface is similar to the interface used in the setup process, see fig. 6 b.

Step S702, a user sequentially selects keys on a multi-dimensional keyboard to input a check password, and presses a confirmation key after inputting is completed;

in step S703, the terminal device 103 obtains password verification information input by the user on the multi-dimensional keyboard, where the password verification information includes a password set displayed by each key selected by the user and an order in which the keys are selected by the user.

Step S704, the terminal device 103 sends the password verification information input by the user to the authentication server 120;

Step S705, the authentication server 120 authenticates the server 120 to obtain the reference password set by the user according to the user identification, and verifies whether the received password verification information is correct according to the reference password of the user;

when each bit of reference password is contained in each password set sequence of the password checking information and the corresponding password sets are ordered, the password checking is correct, and the password checking is successful.

Step S706, the authentication server sends the verification result to the terminal device 103;

in step S707, the terminal apparatus 103 prompts the user for a verification result on the password input interface.

In steps 701 to 704, the terminal device 103 may display the multi-dimensional keyboard for the second time according to the confirmation key operation information of the user. The second displayed multi-dimensional keyboard has at most one identical password displayed on the same key compared with the first displayed multi-dimensional keyboard. The user sequentially selects keys on the multi-dimensional keyboard to carry out second input, and presses a confirmation key after the input is completed; the terminal device 103 obtains information input by the user on the multi-dimensional keyboard for the second time, which includes the password set displayed by each key selected by the user and the order in which the keys are selected by the user, and transmits the information to the authentication server 120.

The authentication server 120 may determine whether the verification password is correct again using the first method, and determine that the verification password is successful if both are correct. The authentication server 120 further obtains the verification password input by the user in a corresponding bit intersection manner according to the first password verification information and the second password verification information. And judging whether the verification password is the same as the reference password, if so, returning the indication information of successful verification to the terminal equipment 103, and if not, returning the indication information of failed verification to the terminal equipment 103.

In practice, the check passwords are obtained, and the check result is judged by using whether the check passwords are the same as the reference passwords or not, which is equivalent to respectively judging whether each reference password is contained in the corresponding ordered password set or not.

If the authentication server 120 cannot obtain the password to be checked input by the user according to the first password checking information and the second password checking information, a prompt message of password input error is returned. After receiving the prompt information of successful verification, the terminal device 103 may execute a subsequent service flow, and if the prompt information of failed verification or incorrect password input is received, prompt the user on the password input interface, and perform a corresponding subsequent flow according to the operation selected by the user. For example, if the user selects to end, the password input interface is closed, the verification process is ended, and if the user selects to re-input the process, the execution is resumed from step 701.

In summary, if the reference password is L bits, the password verification method specifically includes the following three steps:

firstly, according to L keys selected by a user on a multi-dimensional keyboard and a selection sequence, respectively obtaining password sets displayed on the L keys selected by the user, and arranging the password sets according to the selection sequence to form an L-bit password set sequence, wherein when each reference password in the L-bit reference passwords is contained in a password set corresponding to the ordering in the L-bit password set sequence, the verification result is successful.

Secondly, obtaining L keys and a selection sequence selected by a user on the multi-dimensional keyboard at least twice according to the L keys and the selection sequence selected by the user on the multi-dimensional keyboard; respectively obtaining corresponding L-bit password set sequences; and aiming at the L-bit password set sequence obtained each time, when each password in the L-bit reference password is contained in the password set corresponding to the ordering in each L-bit password set sequence, the verification result is successful.

Thirdly, obtaining L keys and selection sequences selected by a user on the multi-dimensional keyboard at least twice according to the L keys and the selection sequences selected by the user on the multi-dimensional keyboard, and respectively obtaining L-bit password set sequences corresponding to each time; and intersecting each set with the same order in the L-bit password set sequences obtained each time to obtain an L-bit check password input by a user, and when the L-bit check password is the same as the L-bit reference password, successfully checking the result.

The second and third modes are essentially the same.

The multidimensional password technology provided by the application can be applied to occasions such as mobile phones, computers, servers and the like where program jump and subsequent operation can be performed only by inputting password authentication identities. When the information with lower security such as the mobile phone number needs to be input or the check information needs to be displayed, the mobile phone number can be used as a single-dimension keyboard through program control. When privacy information with higher levels such as passwords is input, the keyboard can be used as a high-dimension keyboard, and has good compatibility.

And displaying the password random determination of different dimensions on each key on each multi-dimensional keyboard. In one business process, when each time is displayed, the key element set displayed on the same key at each time can only have the same password later, so that the uniqueness of the password intersection on the keys with the same ordering is ensured when information is input twice.

The method is characterized in that a specific multi-dimensional keyboard dynamic display control method is provided, so that only one password is included in the intersection of a password set displayed on any two keys in a multi-dimensional keyboard displayed each time in a business process, N keys are taken as an example of the multi-dimensional keyboard, and when the multi-dimensional keyboard is displayed each time, the password of any one dimension displayed on the N keys is kept unchanged based on the previous display; and moving at least one key to display in a mode of keeping the sequence unchanged for the passwords displayed on the keys in each dimension except any dimension, wherein the numbers of the keys correspondingly moved in each dimension are different. In the above method, the display positions of the N keys may be further rearranged.

Taking N as 10 as an example, after the user finishes the first input on the multi-dimensional keyboard displayed for the first time, during the second time, all password positions in dimension 1 (number) are kept unchanged, all password positions in dimension 2 (number color) are shifted to the right by 1 bit, all password positions in dimension 3 (pattern graph) are shifted to the right by 2 bits, all password positions in dimension 4 (background color) are shifted to the right by 3 bits, and a dynamic keyboard is generated.

Since in this example the numbers are displayed on the background color, to avoid the situation that the number color and the background are the same when each code is shifted, the code of dimension 2 (number color) and the code of dimension 4 (background color) are compared before each generation of the dynamic keyboard, and if the two are the same letters with different cases, the code positions of dimension 4 (background color) are all shifted to the right by 2 bits, and the multi-dimensional keyboard is regenerated. Of course, in order to ensure that the combination of similar colors (such as orange and yellow) does not generate the situation that the numbers are not easy to distinguish, the similar colors are respectively selected to be combined with color values with larger chromatic aberration so as to be distinguished.

When the user inputs the password to be checked, the display control method of the multi-dimensional keyboard is completely the same, and is not repeated here.

According to the password verification method provided by the application, due to the fact that the multi-dimensional password is used, the password decoding difficulty is high, and a better peeping prevention effect is obtained. The reason is that the password has dimensions M, and the password in each dimension is K (typically K >M) and the number of cipher bits is L, then when the cipher input process is completely snooped or recorded, the possible cipher combinations also have ML kinds. If the complete input process is not snooped, the possible combination of passwords is (M.times.K) ^L A kind of module is assembled in the module and the module is assembled in the module. In addition, the password setting process and the password input process both adopt dynamic algorithms to generate keyboard display interfaces, namely the input display interfaces are different each time, so that the password decoding difficulty is higher. Even if the password is maliciously snooped by others, the password cannot be decoded, and information leakage and property loss are avoided.
